nUiviriNG 'PUSH-CAE..

To all whom t may concern:

I inveiitioii,such as will enable others skilled' a rotary platformfand equipped to facili-l tate the dumping of the contents ofthe carA y Be it known that I, Griioiicii C.WoR'rMAN, citizen of the United States', 'residing at thevr city and:` countyof Denverfand State of Colorado, have invented certain new and useful Improvements in 'Dumping Push- Ca'rs; and I do ydeclare the following to be a full, "clear, and exact description of the inthe art-,towwhich appertains to make anduse the same, reference being had to; y I

struction, one 'ofthe bodymembers being shown tilted iii-the dumping position.

the'- accompanyingv drawings, and to the characters of referencev marked thereon,`

which form a part of this' specification.

` My invention relates to improvements in push cars of such construction that the' car body or bodies arehingedly connected with bodies. Preferably yeach car is equipped with a pair of body members the individuals i of, which arev independently tiltable for ydumping purposes.

Inniy present improvement provision is' made whereby the car body members may of the structure when for any reason it may be lnecessary vor desirable to do so as,` for instance, when a train is approaching and the push cai" must be 'removed from the track in'order to let the train pass. In this p truck equipped with a central bushing and event the platform with which the body V members are pivotally connected may be lifted from the trucktogether with` the body j'slidable bars which, when in their normal becomes necessary or desirable to dump the' cars, these bars aremoved endwisefar" enough to disengage them from one ofthe body members after which the otherlmember be tilted to the dumping position by i' "rantarranged adjacent the body member to-v disengaging a spring-heldfdog from a quadbe dumped'. "Furthermore each vbody mem# f ber is equipped with a longitudinallyl exi- Ltensible'handle bar structure which is oper- 'ably connected with :an end gate of the car 'whereby the end gate maybe opened and closed atwill.' By'means of this structure v the end 4gate may i be gradually-opened be readily detached from the truck member .meinbersi` The structure is equipped withwhereby theescape of the-contents may be regulated-at`will, such `escape beingcut of 'asisoon as desired. l

Having bi'i'efiy `outlined my f improveinen I., willI proceedto describe the samel in detail, j reference being made v, to the accompanying drawing in which is illustrated an embodiment thereof. Y Y y' thisdrawing: Y

Let the numeral 5 designate ,the push car truck composedfof wheels 6, a frame 7 and a main platform 8. This structure, so far as the. elements mentioned are concerned, is

Iofordinarylbuild.i l v.

` improvement. commences with the track ring 9 which is equipped with -depending studs or pins 10 adapted to enter 'recesses of counterpart shape formed in the platform 8 of the truck. By virtue of this construction the ring 9 may be'readily applied and as readily removed from the truck. Furthermore, the central portion of the truck as illustrated'r in. the drawing is equipped with a. bushing 12 which enters a central opening 13 formed in the truck platform. rThis bushing extends slightly above the surface of the platform and is expanded somewhat as shown at 14s, this expanded portion as shown in the drawing being of the same thickness as thetrack ring9.

Above the track ring 9 the structure is equipped with a rotary platform 15 which is connected with the main platform 8 by means of a king` bolt 16 whichpasses through an opening formed in the bushing 12, its head 17 yengaging the upper surface of the rotary platform. 15 aroundv -a--central opening 18 formed in thezrotary platform. The lower portion ofthe king bolt below the platform 8, is provided with a transversely arranged opening adapted to receive a locking pin 19 which is springheld in locking engagement'with; the king, bolt and also enters registering openings 20 formed 1n blocks 21 `arranged between the platform 8 and the framework 7 of the truck.

pin in locking engagementv with the king bolt;l The spring 22 is located between a stop 23 mounted on the pin and aperforated lug 241 mounted on the platform 8. and throughv which the pin. 19 passes. r1`he outer extremity 25 of the pin 19 is shaped to facilitate hand manipulation. Asv shown in the drawing this extremity of the pin 19 is bent approximately at right; angles to its `body portion, thus making it practicable for the user of the push car to reach underneath theA platform. 8 from one side of the car and movethe pin sufliciently against the tension of spring 22 vto disengage it from the king bolt 17, when it becomes necessary to remove the body members 26 of the structure from the truck.

rlhis rotary platform 15 is equipped with small wheels 27 which are journaled in angle brackets 2S-secured to the lower surface of the said platform. These wheels engage the circular track 9 and facilitate the rotation of the platform 15.on the truck whereby the body members of the carmay be arranged to dump their contents in anydesired direc tion as circumstances may require.

As shown in thedrawing, and `as. heretofore intimated, thecar is equipped with two body members-26 'which consist simply of boxes, preferably of rectangular shape and hingedly'connected with the rotary platform r 15 as shown at 29.

As illustrated inthe drawing, the two body members are arranged end to end and in such relation that either may be dumped independently of the ThisV locking pin is equipped with a spiral s prmg, 22 normallyV under tension to maintain the.

other. It will be understood that the body structure of thecar together with the rotary platform 15 may be turned upon the king bolt 16 whenever it may be desired to do so.

In order to'maintain each body member 26 in the upright position as shown at the right of Fig. 1, in full lines in Fig. 3 and also in Fig. 4:, the rotary platform 15 is equipped adjacent the body member wit-ha notched quadrant 30 adapted to be engaged by a locking dog 31 which is normally springheld in engagement with a recess `of the quadrant. The spring 32 which` acts on the dog, is secured .to the ycar body at one extremity as shown at 33 but its opposite extremitylis connected as shown at 34:with; the arm of the dog. Also connected with the arm 35of the dog is a vcable or -other suitable connectionA 36 which passes through a guide 37 near the outer end of the body memloei` and extends downwardly in positionn to be readily grasped by the ,user of the car for the purpose of disengaging the dogfroin its coperating quadrant when itis desiredto dump the correspondingA body member of thecar. It will be understood Vthat as force isapplied to the cable 36in the direction of' the arrow a, (see Fig.` 3) the-arm 35 of the dog will be moved in the direction of the pull on the cable and the spring 32 stretched sufficiently to disengage the dog from the quadrant after which the car may betilted as hereinafter explained.

The body members ofthe car are equipped on each vside with a pair-.of bars ,38 which slidably engage guide loops 39 mounted .on the side walls of the two'body members 26. As shown in thedrawing, these bars .38 are arranged one aboveanother on the opposite sides ofthe car. rlhe upper pair of bars 38 oneloneach side are connected at .their opposite extremities, whiche are perforated for the said bars must be removed. In4 practice one pair of bars will bemovedinr one direction and theotherpairof bars in the opposite directiony when it is desired toy dump one or both body members. In this way the proj ecting portions of each pair of bars constitute manipulating, handles whereby` the` car bodies may be tilted for dumpingjpurposes and raised to their normal position as may be` desired. As shown. in the drawing, the body members are approximately centrally` hinged,- their outer extremities being preferably slightly farther from the axis of the hinge than their inner extremities whereby when the bars 38 are properlyY manipulated and any dog 31 unlocked, the body me `ber will automatically assume the tilted or dumping position. Itshould be explained, however, that theexact location of the hinge pin with reference to the opposite extremities `of the cars is not vital since it may be so located lthat slight downward pressure of the protruding extremities of the pair of bars 38 may be necessary in order to over-balance the car body for dumping purposes. The protruding extremities or bars 38 however, are essential in restoring the car body to its normal orupright position after the dumping or partial dumping of said member.

Furthermore, each body memberl 26 is equipped with'a centrally located extensible handle bar, 41 hingedly connected with the inner extremity of the car atthe top as shown at 42, each of these handlebars being composed of two parts 43 and 44 to each of which is attached, as shown at 45, a metal loop or guide 46 through which the other member passes. Normally, or when the cars are fin their upright position and untilv the discharge lof the contents, either in whole or in part, of the body member is required, each handle bar is adjusted as bestv shown in Fig. 4 whereby only the short .handle end 47 of one member of the bar extends beyond the outer extremity of the lbody member.

vThe upper member 43 of each ,handle bar engages a loop 48 which extends above the upper edge of the car body and forms a connection with the handle bar f or the purpose of manipulating the end gate 49 of the body member when it is desired to allow the contents of the car, either all or in part, to escape. Before opening the `end gate, the

corresponding handle bar will be extended if' or drawn outwardly preferably to its vrlimit of movement. The partial extension of one of these handle bars, is indicated in Figs. 1 and 2. When this is` done the operatorwill have the advantageofrelatively powerful i leverage in opening the end gate 49 or slidable end member of` the car bodyV to which i the loop 48 is secured as shown at 50. Y

From theA4 foregoing description the use I ,and Yoperation of my improved .dumping push car will be readily understood. The normal position of the parts of the entire car structure is illustratedin fullzlines in Fig. `3. This is the normal position of .the

car during loading. VIt, .isi-evident, however, ithat 1f 1t is rmore convenient to load the car,

as in manyv instances it willl be,lthe body members may be shiftedr 4to the lposition shown in Fig., 4 whereby they extend at right angles to the direction of travel of a car on a track or at any other angle thereto `as convenience'may dictate',t lInanyievent, as soon as the car-1s loaded 1t may be moved along the track for purposes of repair bythe 'discharge of its contents as may belrequired.

ever, if it is desired to dump'the ent-ire contents of the body Vmember in acsingle placel the end gate may be raised to its full height or completely opened whereby'the contents will quickly "escape down theincline formed by the tilted body member.

vAsshown in the drawing, the car structure is equipped with suitable brake mechaynism composed of brake beams 51 carrying vshoesy 52, each beam being connected by means of a rod 53 with a lever 54 fulcrumed at 55 and whose outer extremity is connected asshown at'56 with a rod or cable`57 one `extremity ofwhich is connected asshown at 58 with a lever 59 fulcrumed on the .truck as shown at 60. This lever, as shown '1n the drawing, 1s composed of ktwo armsarranged manner indicated by dotted lines in Fig. 3.l

The lever is then moved in the direction indicated ,by the dotted arrow, whereby sufficient force is supplied to the lever 54 to force the brake shoes against the 'wheels of the truck for braking purposes.

. ttention is called to' the'. factl that the rotary platform 157012'` the structure is equipped with a number of upwardly projecting short pedestals 64 which are of sufficient heightto engage the bottoms of thecar bodies when thelatter are in the horizontalpositio'n (SeeiFig. 3)', the height of these pedestals corresponds to thev height of Ithe hinging 'structure of the :body members o f the car.

' The king bolt :16"is preferably provided with a lug 70 yadapted to engage a counter'- part recess 71 formed in thesplatform memlvloer 15, wherebythe,` said pin is prevented from'rotating inthe platforinff'lhe lu 7 0' and the'recess 'Z1 'are so disposed thatw yen the' PHS in place the saidplatform member the vopeniljignin' the lower extremity of the pin for the rod, 19, is in 'registerwiththe' fopenings20'inthe blocks or'beams21.
